Yeah this is one of those oft repeated pieces of advice that has never made sense to me. It's always worded such that it sounds like the effects of any sleep deprivation ever are permanent.

I guess what they mean is that if you don't sleep for 24 hours and the next day you sleep for 16 (to make up for the lack of sleep in the previous day), after you wake up you still wont be as good (mentally, immune-wise, etc) as you'd be if you've slept properly on both days. Obviously that can be corrected over a few days period and you get back to normal (except if you had abused yourself will lack of sleep over many years, in which case you might have indeed incurred some permanent damage).

  He seems to be saying that you won't sleep for 16 hours the second night.

    Well, as for that, you'd be surprised.

Of course they are. You'll learn less in your sleep deprived states, Which are days you aren't going to get back. Your sleep deprived self will also be better at creating tech debt, which takes away time from the future.

  >You'll learn less in your sleep deprived states, Which are days you aren't going to get back. That's not what a description of what the professor says in the article, or the way we mean it. Of course you won't get "chances to learn" or "tech debt" back. This is not about it. TFA talks about a physiological debt that you can't repay.

    I don't know how to measure the physiological debt, and the person asking the question was not sold on the physiological debt.

  That is an odd perspective. That's like saying that the damage from a twisted ankle is permanent, since you'll never get back the two days of lost activity. From that point of view, all injuries are permanent.

    Well, yes. But the difference comes in the nature of the deficit you can't get back. By not sleeping, you magically turn some fraction of the previous day's learning into wasted time, just throw it away. The appropriate analogue in the twisted ankle case would be if the twist magically "un-walked" the 4 miles you walked the day before, and that increment of weight loss and cardio health were lost to you. This is of course not the case.. :)

    You generally don't recover fully from twisted ankles. Most injuries are in fact permanent in a certain sense. You heal, but not 100%. I saw this analogy upthread, and it's changed how I consider sleep deprivation. Brain injuries may not be different from physical injuries.
